The outer surface of each screw piece 205 is The bottom of each auger piece 205 is in the same horizontal plane as the bottom of each circular tube 203, the top of each auger piece 205 is in the same horizontal plane as the top of each circular tube 203, the interior of each top cover 206 is connected to the interior of each circular tube 203, the bottom end of each rotating rod 204 is installed with the output end of each motor 201, the cooling tower body 1 includes a tower body 101, each motor 201 is installed at the bottom of the tower body 101, and each set of brackets 202 is installed inside the tower body 101. At the bottom of the wall, the bottom end of each rotating rod 204 is movable through the bottom of the inner wall of the tower body 101. A water pump 102 is installed on one side of the tower body 101. The interior of the input end of the water pump 102 is connected to the interior of the water outlet near the bottom of the inner wall of the tower body 101. A multi-head sprinkler 104 is installed on the top of the inner wall of the tower body 101. The input end of the multi-head sprinkler 104 is movable through the top of the inner wall of the tower body 101. A water pipe 103 is installed at the output end of the water pump 102. The output end of the water pipe 103 is installed with the input end of the multi-head sprinkler 104. The interior of the tower body 101 is provided with a plurality of sprinklers. A condenser 105 is provided, and the output end and the input end of the condenser 105 are fixedly passed through one side of the inner wall of the tower body 101. The condenser 105 is located below the multi-head sprinkler 104. Two symmetrical support blocks 106 are fixed to the bottom of the tower body 101. An air duct 107 is fixedly passed through one side of the inner wall of the tower body 101 near the bottom. A fan 108 is installed at the input end of the air duct 107. A controller 109 is installed on the front surface of the tower body 101. The water pump 102, the fan 108 and multiple motors 201 are all electrically connected to the controller 109.

[0026] The effect achieved is that when hot circulating water is needed for cooling operation, the input end of the condenser tube 105 is first installed together with the output end of the pipe for conveying hot circulating water, and then the output end of the condenser tube 105 is installed together with the input end of the pipe for recovering the cooled circulating water, and then the controller 109 is connected to the external power supply through the prepared power cord, and then the controller 109 is turned on and the usage program is set, and then an appropriate amount of low-temperature clean water is injected into the bottom of the inner wall of the tower body 101 through the air inlet at the top of the inner wall of the tower body 101 (the height of the low-temperature clean water is at the same level as the top of the circular tube 203). When everything is ready, the controller 109 is used to start the fan 108, and the started fan 108 will use The cooperation of the air inlet at the top of the inner wall of the tower body 101, the air inlet on the other side of the inner wall of the tower body 101 and the air duct 107 first sucks the low-temperature air in the environment into the interior of the tower body 101, then transports it to the interior of the air duct 107, and then transports it to the interior of the fan 108, and then transports it back to the environment for a new cycle. After that, the water pump 102 is started by the controller 109. At this time, starting the water pump 102 will cooperate with the water outlet near the bottom position on one side of the inner wall of the tower body 101 to draw away the low-temperature clean water at the bottom of the inner wall of the tower body 101, and transport it to the interior of the water pipe 103, and then transport it to the interior of the multi-head sprinkler 104, and then spray it out from each nozzle on the multi-head sprinkler 104, spray it on the outer wall of the condenser 105, and finally flow back to At the bottom of the inner wall of the tower body 101, a new cycle is carried out. When low-temperature air flows inside the tower body 101 and low-temperature clean water circulates inside it, the pipe for conveying hot circulating water conveys the hot circulating water to the inside of the condenser 105. When the hot circulating water flows inside the condenser 105, the circulating water inside the condenser 105 can be cooled with the cooperation of the flowing low-temperature air and the low-temperature clean water falling on the outer wall of the condenser 105. The cooled circulating water will then be conveyed to the pipe for recovering the cooled circulating water and then transported away. At the same time, the hot air after heat exchange will be diverted to the environment, and the hot clean water will also fall to the bottom of the inner wall of the tower body 101. When the hot clean water reaches the bottom of the inner wall of the tower body 101, it will be cooled from the bottom of the inner wall of the tower body 101. The low-temperature air coming in from the inlet on the other side of the inner wall of the tower body 101 will take away the heat in the hot water returning to the bottom of the inner wall of the tower body 101. When the hot water returning to the bottom of the inner wall of the tower body 101 needs to be cooled quickly, the controller 109 is used to start all the motors 201. At this time, each motor 201 that is started will drive the rotating rod 204 connected to it to rotate, and each rotating rotating rod 204 will drive the auger piece 205 connected to it to rotate. When all the auger pieces 205 are rotating, each rotating auger piece 205 will, with the cooperation of a corresponding set of brackets 202 and a corresponding round tube 203, flip the hot water at the bottom of the inner wall of the tower body 101 from the bottom to above the water surface, and then transport it to the inside of each top cover 206.The hot water then passes through each cylindrical hole 207 opened in each top cover 206 and falls back to the bottom of the inner wall of the tower body 101. At this time, the low-temperature air entering from the inlet on the other side of the inner wall of the tower body 101 cools the falling hot water, which accelerates the cooling rate of the hot water flowing back to the bottom of the inner wall of the tower body 101.

[0027] Working principle: When hot circulating water is needed for cooling operation, first install the input end of the condenser pipe 105 together with the output end of the pipe for conveying hot circulating water, and then install the output end of the condenser pipe 105 together with the input end of the pipe for recovering the cooled circulating water, then connect the controller 109 to the external power supply through the prepared power cord, then turn on the controller 109, set the usage program, and then cooperate with the air inlet at the top of the inner wall of the tower body 101 to inject an appropriate amount of low-temperature clean water into the bottom of the inner wall of the tower body 101 (the height of the low-temperature clean water is at the same level as the top of the circular tube 203). When everything is ready, use the controller 109 to start the fan 108, and the fan 108 started at this time will use the air inlet at the top of the inner wall of the tower body 101 to The low-temperature air in the environment is first sucked into the interior of the tower body 101 by the cooperation of the air inlet at the top, the air inlet on the other side of the inner wall of the tower body 101 and the air duct 107, and then transported to the interior of the air duct 107, and then transported to the interior of the fan 108, and then transported back to the environment for a new cycle. After that, the water pump 102 is started by the controller 109. At this time, starting the water pump 102 will cooperate with the water outlet on one side of the inner wall of the tower body 101 near the bottom to draw away the low-temperature clean water at the bottom of the inner wall of the tower body 101, and transport it to the interior of the water pipe 103, and then transport it to the interior of the multi-head sprinkler 104, and then sprayed from each nozzle on the multi-head sprinkler 104, sprayed on the outer wall of the condenser 105, and finally returned to the bottom of the inner wall of the tower body 101 for a new cycle. 101 , the hot air will be transported to the bottom of the inner wall of the tower body 101, and the hot water will fall to the bottom of the inner wall of the tower body 101. When the hot water reaches the bottom of the inner wall of the tower body 101, the low-temperature air coming in from the inlet on the other side of the inner wall of the tower body 101 will be cooled. The heat in the hot water returned to the bottom of the inner wall of the tower body 101 will be taken away. When the hot water returned to the bottom of the inner wall of the tower body 101 needs to be cooled quickly, the controller 109 is used to start all the motors 201. At this time, each motor 201 started will drive the rotating rod 204 connected to it to rotate, and each rotating rotating rod 204 will drive the auger piece 205 connected to it to rotate. When all the auger pieces 205 are rotating, each rotating auger piece 205 will, with the cooperation of a corresponding set of brackets 202 and a corresponding round tube 203, flip the hot water at the bottom of the inner wall of the tower body 101 from the bottom to above the water surface, and then transport it to the inside of each top cover 206, and then pass through each cylindrical hole 207 opened on each top cover 206.It falls back to the bottom of the inner wall of the tower body 101. At this time, the low-temperature air coming in from the inlet on the other side of the inner wall of the tower body 101 is used to cool the falling hot water, that is, to accelerate the cooling speed of the hot water flowing back to the bottom of the inner wall of the tower body 101, thereby ensuring the cooling effect of the closed cooling tower.

[0028] The two air inlets of the tower body 101 are located at the top of the inner wall of the tower body 101 and the other side of the inner wall of the tower body 101 respectively;

[0029] The tower body 101 is composed of two symmetrical shells.

[0030] Among them, the water pump 102, multi-head sprinkler 104, condenser 105, fan 108, controller 109 (PLC controller), motor 201 and auger 205 are all existing technologies, and their models can be selected according to actual conditions. No further explanation is given here.
